prevent Upload Large Files .Net

[Kilic Beg]

Hi,

I want to prevent user to upload files larger than 2MB.
If they try to upload I want to redirect them to a error page (ex: File size
larger than 2 MB )..
right now I get a page break "The page cannot be displayed"

I tried to update the Global.asax.cs file this is the code

protected void Application_BeginRequest(Object sender, EventArgs e)
{
long MAX_CONTENTLENGTH = 2097152;
if (Request.ContentLength > MAX_CONTENTLENGTH) {
//Response.Write("File is to big");
Response.Redirecty("Error.html");
}
}

I put the same code also into
protected void Application_Error(Object sender, EventArgs e)
method..

still page break..

where and how can I catch that and redirect to a friendly error page.
do I have to use a third party product for that ?

Please help !!!

Thanks

Hi,

you can also set this on web.config. see <httpRuntime> element and
especially maxRequestLength setting
http://msdn.microsoft.com/library/d...-us/cpgenref/html/gngrfhttpruntimesection.asp

Just note that this effects entire application at once (if it is config file
on app root, on subfolder you can limit it to folder/page level)

My problem is not setting the file size limit.

I want to display an error message when the users tries to upload a file
large then in maxRequestLength definied.

right now I have this in my webconfig

<httpRuntime executionTimeout="90" maxRequestLength="4096"
useFullyQualifiedRedirectUrl="false" minFreeThreads="8"
minLocalRequestFreeThreads="4" appRequestQueueLimit="100" />

If the users tries to upload files larger than 4MB he will get a page break
"The page cannot be displayed"..
I want to display a friendly page... (ex: saying the file you trying to
uploading is larger than 4MB)

Kilic,

Not sure how to check the request size, but if you're using one of the
..NET file upload controls (System.Web.UI.HtmlControls.HtmlInputFile or
2.0 FileUpload) you could simply write

System.Web.UI.HtmlControls.HtmlInputFile File1;

if (File1.PostedFile.ContentLength > MAXFILESIZE) {
Response.Redirect("filetoolarge.aspx");
}
else {
// Save the file on the server
}
